event handler is not working with form

[cmotor]

I am submitting a form with the onclick attribute. When my form is submitted it is supposed to call a javascript I am using for security. Cool menus submitts the form but does not set off the javascript: FixBusi(this);

Code Below:

oCMenu.makeMenu('top2','','','','','86','14','imag es/navbar/viewcartoff.gif','images/navbar/viewcarton.gif','','','','','','document.F_viewcar t.submit();')

<font color="blue">
<td><form name="F_viewcart" target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post" onsubmit="FixBusi(this);">
<input type="hidden" name="business" value="slsales783326@earthlink.net">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="display" value="1"></form></td></font id="blue">
